The hottest day anticipated in a string of blazing ones lifted temperatures in some areas into the 90s before 10 a.m. on Sunday and brought with it potentially nightmare conditions for firefighters.
A red-flag warning issued by the National Weather Service on Saturday also remained in effect until 9 p.m., as breezy and gusty winds complemented the rising temperatures.
“It’s not that the winds will be that strong, but they’ll be noticeable,” meteorologist Roger Gass said. “If a fire does begin, these are the kind of conditions that could allow it to go out of control really fast.”
The winds were expected to be from the north and blow from 10-15 mph, according to the NWS, and areas above 1,000 feet in the East and North Bay Hills, the Santa Cruz Mountains and the Diablo Range all were in the red-flag zone.
Temperatures wasted little time moving upward, as nearly all Bay Area locations were running 5-10 degrees hotter at 9:30 a.m. than they were at the same time Saturday.
In San Jose, it was 75 degrees at 9:30 a.m., and Gass said the the city’s 82-year-old record of 96 degrees could fall. In Livermore, in the far East Bay, the gauge already read 79 degrees, en route to what Gass said would be temperatures over 100 degrees.
The thermomenter also was expected to crack the century mark in Brentwood, Antioch, Pittsburg, Concord and Gilroy, and move into the 90s throughout the Santa Clara Valley and the rest of Contra Costa County, Gass said. In Pittsburg, it was 90 degrees at 9:45 a.m.

The projected forecast high in Oakland was 86 degrees, and 77 degrees in San Francisco.
“This will definitely be the hottest day,” Gass said.
Relief is expected to arrive Monday.
“The lack of marine influence we’ve been having is going to go away,” Gass said. “We’re going to get a strong marine push off the coast, and that will cool things down.”
Temperatures on Monday were expected to be cooler by as many as 10 degrees from their Sunday highs.
